Key takeaways

Two severe PHP security flaws are rated 9.2 out of 10 for severity.

Around 1.3 million internet-connected systems could be affected by the vulnerabilities.

Security firm Sansec expects large-scale attacks to begin within 15 minutes of patches becoming available.

The vulnerabilities are tracked as CVE-2026-109618 and CVE-2026-109619.

Web administrators face urgent warnings as two severe security flaws in PHP threaten millions of sites, with cybersecurity professionals predicting widespread attacks within minutes of patch availability. Operators need to ready themselves for immediate updates because the vulnerabilities enable bad actors to execute malicious code on vulnerable web servers.

PHP maintainers intend to issue patches for both issues, which each carry a severity rating of 9.2 out of 10. Web managers must prepare to apply these updates the moment they launch.

Why the Flaws Are Highly Dangerous

PHP serves as a common programming language supporting numerous websites and web applications. It drives WordPress, various other site-building platforms, and internal business tools.

An estimate from one security researcher suggests that roughly 1.3 million internet-connected systems are at risk.

Successful exploitation of these bugs could trigger severe security issues for compromised systems. The reported severity and massive adoption of PHP mean these vulnerabilities worry website operators everywhere.

Administrators need to track official bulletins and apply security patches immediately upon release.

Attackers Could Strike Within Minutes

Security organization Sansec anticipates massive attacks to start within 15 minutes after patch distribution. Additional cybersecurity firms like Wordfence and Huntress have similarly advised administrators to ready themselves immediately.

Administrators should determine who handles PHP updates, audit which sites and apps rely on it, and schedule a maintenance window beginning at 14:00 UTC. They should also apply fixes sooner if required.

Specialists advise backing up site and database files while watching PHP.net for updates. Certain experts even recommend shutting down nonessential systems temporarily until patching occurs.

Leaked Demo Raises Alarm

This alert stems from reports regarding unreleased information about the bugs leaking onto the internet. The leaked content supposedly featured a video displaying an exploit utility named PHP2Shell, capable of executing code on web servers.

The demonstration supposedly displayed the tool functioning against multiple major platforms, including WordPress 7.1.3, MediaWiki 1.46.2, phpBB 3.3.17, Magento 2.4.9, Joomla 6.2.0, Laravel 13.36.0, Laravel 8.83.29, Symfony 8.1.9, Drupal 11.4.10 and WHMCS 9.0.9.

Every single one of these platforms relies on PHP. Nevertheless, the original leaked report remained unfound, and its assertions lack official verification.

Security firm watchTowr stated that the report asserted every PHP iteration starting from PHP 5 in 2004 could be vulnerable. The firm also verified the authenticity of both vulnerabilities, designated as CVE-2026-109618 and CVE-2026-109619.

PHP maintainers noted that patches might arrive sooner than scheduled if flaw details leak publicly or attacks begin.
